Landing in the air regulator of ventilation tubular type of so constituting, when the drive compression machine made kind of refrigeration cycle running beginning, the refrigerant that has been compressed in compressor circulated in refrigerating circulatory device 16.
Simultaneously, pressure fan 10 is driven, and the air that is disposed at the Machine Room of this air regulator is imported to indoor heat converter 9 from sucking grid 2 by filter 8, carries out heat exchange herein with by the refrigerant in the indoor heat converter 9.The air that has carried out heat exchange at indoor heat converter 9, discharge and be inhaled into the suction oral area of the fan box 13 that constitutes pressure fan 10 from indoor heat converter 9, be directed to and blow out ventilation duct (duct) by being formed on blow-off outlet 7 on the housing 1, blow out ventilation duct by this and blow out, to by air-conditioning indoor heating or refrigeration from being arranged on by the indoor blow-off outlet of ceiling in the air conditioning chamber etc.
And the water from watering importing water pipe imports the fan loop assembly from the auxiliary water heat exchanger, and carries out heat exchange with the air that carried out heat exchange with heat exchanger in the main chamber.Then, according to different during with the refrigeration of interim or warming operation when the refrigeration in common period or the warming operation,, switch to three-way change-over valve and to be by main water heat exchanger or directly to import water out.
Perhaps, when being reached design temperature, also can stop the running of compressor, be replaced into and only make the running of fan loop assembly by the temperature of air conditioning chamber.At this moment, during refrigeration cold water is directed into the fan loop assembly from cooling tower, during heating warm water is directed into the fan loop assembly from boiler.Pressure fan 10 continues to be driven, and cold wind or warm braw are blown out in by the air conditioning chamber.That is, can not can change ability expeditiously according to air conditioner load, but can carry out the operation of air conditioner of so-called soft feeling as with convertor device (inverter apparatus) control kind of refrigeration cycle.
When carrying out kind of refrigeration cycle, be housed in electric component D electrical control in the electric part box 18 with the various electrical components headed by the above-mentioned compressor.Heating during electric component D energising, so the temperature in the electric part box 18 rises.When rising to set point of temperature, do not have the temperature sensor (temperature sensor) of expression to detect among the figure, and transmit the driving signal to sending out the hot fan 20.
By the driving of sending out the hot fan 20, the heat that will be full of in the electric part box 18 is fetched into electric component chamber 15.Because electric component chamber 15 is to separate narrow and small gap electric part box 18 is surrounded, thus this gap once be full of from the heat of electric part box 18 discharges, and the heat of whole discharges is sucked path 23 guidings along heat extraction.
Specifically, from the heat of the discharge of electric part box 18 focus on be arranged on that horizontal baffle 17a goes up and the concentrated area at the heat extraction suction inlet 22 of sending out the hot fan 20 side openings.Then, from heat extraction suction inlet 22, through on horizontal baffle 17a, deriving the filter secondary side of side and import as the air of indoor heat converter 9 between the heat exchanger primary side of side as the air of filter 8 is derived.
As mentioned above, because pressure fan 10 is to be driven with compressor in the kind of refrigeration cycle running, thereby the Machine Room air is successively by sucking grid 2, filter 8 and indoor heat converter 9.Air-supply effect by pressure fan 10 makes the negative pressure state that becomes on the horizontal baffle 17a to a certain degree, will be released to the heat extraction sucking-off expeditiously of electric component chamber 15 from heat extraction suction inlet 22.
Then, the heat of discharge with by (secondary side) after the filter 8, the air by (primary side) before the indoor heat converter 9 mixes, these gaseous mixtures are imported into indoor heat converter 9 and carry out heat exchange.Be imported into by pressure fan 10 then and blow out ventilation duct, from being blown out by the air conditioning chamber.
Because compare the air quantity of pressure fan 10 with the air quantity of sending out the hot fan 20 very big, thereby for the air that imports to indoor heat converter 9 by filter 8, the heat extraction of electric component D can not cause that temperature rises.Even there is small temperature to rise and since these mixing airs at indoor heat converter 9 by heat exchange, thereby the air that is imported into pressure fan 10 can be carried out air conditioning for passing through the state after the heat exchange fully expeditiously by the air conditioning chamber.
That is, when warming operation and during cooling operation, can not influence the heat exchanger effectiveness of indoor heat converter 9 from electric component D liberated heat, on the other hand, heat extractions in the electric part box 18 expeditiously, the temperature that can suppress in the electric part box 18 rise.Therefore, to the harmful effect that electric component D can not produce heat, can guarantee to the long term reliability of electric component D.
And because the heat of electric component D can not be discharged in the Machine Room of configuration air regulator, the temperature of Machine Room can not rise, thereby imports to the not rising of air themperature of indoor heat converter 9 from suction grid 2.For example, be at filter 8 under the state of pore obstruction, because heat extraction sucks the secondary side that path 23 is arranged on filter 8, the influence of the hole plug of also not being bullied sucks heat extraction expeditiously.
Top view, vertical side view, the horizontal side view of Fig. 7 (A), 7 (B), 7 (C) expression horizontal baffle 17a.Along being arranged on the periphery of the heat extraction suction inlet 22 of this horizontal baffle 17a, the flange (lib) 25 of specified altitude is set with being integral with horizontal baffle 17a.Because this flange 25 is the periphery settings along heat extraction suction inlet 22, thereby can prevent the dewfall of heat extraction suction inlet 22 peripheries on horizontal baffle 17a, can prevent that perhaps the water that dewfall is melted from dropping onto electric component chamber 15 from heat extraction suction inlet 22.
Owing to the electric part box 18 that is configured in the electric component chamber 15 is made open architecture for the heat extraction that can carry out electric component D more expeditiously, thereby water droplet immerses easily, and water droplet is easily attached on the electric component D.Therefore, flange 25 is set, positively prevents the immersion of water droplet and can prevent the accidents such as breakage of electric component by periphery at heat extraction suction inlet 22.
Top view, vertical side view, the horizontal side view of Fig. 8 (A), 8 (B), the other forms of horizontal baffle 17a of 8 (C) expression.Along the periphery that is arranged on the above-mentioned heat extraction suction inlet 22 of this horizontal baffle 17a flange (lib) 25 is set, this puts identical with the form of above-mentioned Fig. 7 (A), 7 (B), 7 (C) expression.Be characterised in that herein, further whole heat extraction suction inlets 22 and flange 25 be provided with antidrip lid (drip-proof cover) 30 with surrounding.
This antidrip lid 30 is formed by bending and to see from the side and roughly become コ word shape, and for example the both side ends of left and right sides width is by opening, and the position, top of heat extraction suction inlet 22 and the front and rear part of horizontal baffle 17a are by obturation.Open portion is not limited to end, the left and right sides, can the opening portion that be made of a plurality of holes that separate predetermined distance be set at the position, front and back, also can be arranged on above-mentioned both sides.
So, by possessing flange 25, also possess antidrip lid 30, can more positively prevent the dewfall of heat extraction suction inlet 22 peripheries on the horizontal baffle 17a with opening portion.
And the present invention is not limited to the above embodiments, can change in the scope that does not break away from spirit of the present invention.And, by being carried out suitable combination, the disclosed a plurality of inscapes of the above embodiments can form multiple invention.
